, Application filed July as,

The present invention relates to the manufacture of heels, and particularlyand especially to heels for womens shoes they objects of the invention being to improve upon the c'onstruct-ionof such heels for making the heel better and more economically than heels at present in use. y l

The customary form of high heels for womens shoes are made of a solid block of wood which is usually provided with a leather or cloth cover. The wooden heels will easily split or crack and the cover will come off the heel portion of a womans shoe showingthe internal construction and the manner of fastening the heel upon the shoe; Figure 2 is a transverse section through the same; and

the invention. y

In Figures 1 and 2, the rear portion of the shoe is shown at 1 and the heel at 2 and a rubber lift at 3. The nails for securing the heel upon the shoe and the lift upon the heel are shown at 4:, it being observed that the nails are driven directly into the heelwhich is of such a nature that the nails will hold as readily as in a wooden heel.

The heel is composed of an'integral piece of vulcanized hard rubber so as to be absolutely waterproof, but .which, however, is so constructed and designed that it is light in weight and will receive and hold the securing nails without cracking and as firmly as the usual wooden heel. In addition, the outer surfaces of the heel is of such a character that it will take a high polish so that it may be used without any covering, if desired. As an alternative, it may be made with a rough finish to which the usual cover- Figure 8 is a section of a modified form of 1928. Serial mat/5,431.

ing materials be applied and to which they will ad here more securely than to the wooden heel.

The heel of Figures 1 and 2 comprises a center or core of cellular hard rubber 6. This 1s composed of abody of. rubber of a composition which will be quite rigid when cured,

but which is cellular or honeycombed so that it is light and porous. This is made'b y incorporating in the hard rubber composition, a substance which will volatilize, gasify'or vaporize under the heat of vulcanization and create the numerous small pockets or air cells which are illustrated in the drawing. It has been discovered that this cellular hard rubber will receive a nail driven 'into it and will hold securely so that the heel maybe v nailed upon the shoe and the lift nailed upon the wooden heel.

The center or core of the heel is surrounded with a layer or film of solid hard rubber 7 which is cured with the body or core of the heel and becomes an integral part thereof, the skin or layer of solid hard rubber extending about the upper edges of the heel, Hidethe heel in the usual manner as applied to sired, .so that the heel will fit against the shoe as shown. This outer hard rubber. layer will receive and retain a very high polish so that the heel, as shown, can be used to replace the usual patent leather covered wooden heel.

In Figure 3 is illustrated a different form of heel and in'this viewthere are shown in lays above and below the heel of laminated wood, which are vulcanized in place and which may be used if desired to receive the securing nails, although the presence of the I inlays is not essential. In this form ofheel is also shown the leather or cloth cover 12 which may be employed, the outer surface of the layer 7 about the heel not being polished in this embodiment of the invention, but

being left in such condition that the covering will adhere tothe heel.,

It is obvious that exact conformity with the details which have been shown and de- I scribed is not essential, but these details may be varied within the scope of the invention.

What is claimed is 1. A heel for the uses and purposes. set forth,'comprising a'central body portion of hard. rubber provided with a multiplicity of small air cells-embedded therein, said bod portion being capable 'of receiving and hol ing securing nails driven therein.

2. A heel for the uses and purposes set forth, comprising a, central body portion of hard rubber provided with a multiplicity of small air cells -:embedded' therein, said body portion being capable of receiving andholding securing'nails' driven therein, and an integral layer of solid'hard rubber surrounding the body portion and forming an outer impervious cover therefor.
